MITIGATING ADVERSE EFFECTS OF ETTRINGITE IN MINERAL BINDER COMPOSITIONS
A polymer P is used for improving the effectiveness of a dispersant, in particular a polycarboxylate ether-based dispersant, in a mineral binder composition forming and/or comprising ettringite, and/or for reducing or inhibiting adverse effects of ettringite on the effectiveness of a dispersant in a mineral binder composition, said polymer P comprising:a) at least one monomer unit M1 of formula I: CH2=CHNRCOR' (I)whereby R and R' independently of each other is a hydrogen atom or a methyl group, or where R and R' together form an alkylene chain so as to provide, together with the N atom and the C atom to which they are attached, a cyclic structure, especially a five membered ring;b) optionally at least one further monomer unit M2.
